Abstract

Heat sinks and cooling fans are currently the most common tools for regulating temperature within the application-specific integrated circuits of electronic products. Unfortunately, fans consume additional power; therefore, effectively monitoring ASIC temperatures and reducing the power consumption of fans are crucial. This study employed built-in thermal sensors to monitor the temperature within the ASIC and a boost DC-DC converter to drive cooling fans and improve power efficiency.
